She says the signs weren't there. Until she was able to read between the lines of her daughter's work.

"She was good at showing me what I wanted to see and everything was just smooth sailing. But, she has this side to her that came out in her writing and her art," Piper added. "I never saw this issue of each time something bad would happen in her life, whether it be a breakup or a disappointment or a low grade, that that was just chiseling away at her ability to handle situations."

It's a desperate call for help.

"This is what a survivor looks like," Piper said as she pointed to her face. "It's not easy."

Piper has some words that she would say if she saw her daughter one last time.
